test smart http fetch and push The top level directory "/smart/" of the test Apache server is mapped through our git-http-backend CGI, but uses the same underlying repository space as the server's document root. This is the most simple installation possible. Server logs are checked to verify the client has accessed only the smart URLs during the test. During fetch testing the headers are also logged from libcurl to ensure we are making a reasonably sane HTTP request, and getting back reasonably sane response headers from the CGI. When validating the request headers used during smart fetch we munge away the actual Content-Length and replace it with the placeholder "xxx". This avoids unnecessary varability in the test caused by an unrelated change in the requested capabilities in the first want line of the request. However, we still want to look for and verify that Content-Length was used, because smaller payloads should be using Content-Length and not "Transfer-Encoding: chunked". When validating the server response headers we must discard both Content-Length and Transfer-Encoding, as Apache2 can use either format to return our response. During development of this test I observed Apache returning both forms, depending on when the processes got CPU time. If our CGI returned the pack data quickly, Apache just buffered the whole thing and returned a Content-Length. If our CGI took just a bit too long to complete, Apache flushed its buffer and instead used "Transfer-Encoding: chunked". Signed-off-by: Shawn O.

t5551-http-fetch: Work around some libcurl versions Some versions of libcurl report their output when GIT_CURL_VERBOSE is set differently than other versions do. At least one variant (version unknown but likely pre-7.18.1) reports the POST payload to stderr, and omits the blank line after each HTTP request/response. We clip these lines out of the stderr output now before doing the compare, so we aren't surprised by this trivial difference. Reported-by: Tarmigan <tarmigan+git@gmail.com> Signed-off-by: Shawn O.

t5551-http-fetch: Work around broken Accept header in libcurl Unfortunately at least one version of libcurl has a bug causing it to include "Accept: */*" in the same POST request where we have already asked for "Accept: application/x-git-upload-pack-response". This is a bug in libcurl, not Git, or our test vector. The application has explicitly asked the server for a single content type, but libcurl has mistakenly also told the server the client application will accept */*, which is any content type. Based on the libcurl change log, this "Accept: */*" header bug may have been fixed in version 7.18.1 released March 30, 2008: http://curl.haxx.se/changes.html#7_18_1 Rather than require users to upgrade libcurl we change the test vector to trim this line out of the 2nd request.
